A dumbbell-type [60]fullerene dimer in which both C-60 units are coval
ently attached to a double donor spacer has been prepared by a double
cycloaddition of azomethine ylide to C-60. The CV data indicate that t
he dimer behaves electrochemically as two independent donor-acceptor u
nits. Copyright (C) 1996 Elsevier Science Ltd
